LAMP-BURNER.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed January 2, 1908. Serial No. 408,915.

To all whom it may'concern:

Be it known that I, GEORGE H. RoLrns, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Lamp Burners, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that character of lamp burners in which a frame including air directing members located at the sides of the wick tube and Spreaders located at the edges of the wick tube are utilized for the purpose of properly directing air to the flame, while burning at the end of the wick and spreading said flame to increase its illuminating power.

The present invention has for its object the application of means to the air directing members of a burner of the character named, whereby the efficiency of the flame in the burner is enhanced, and the production of smoke is obviated, due to a more perfect combustion of the carbon in the flame.

Figure I is a top or plan view of my burner applied to a lamp font. Fig. II is an elevation of the burner. Fig. III is an enlarged cross section taken through the air directing members of the burner. Fig. IV is an enlarged cross section taken on line IVIV, Fig. III. Fig. V is a view similar to Fig. III, illustrated in the modification.

In the accompanying drawings:

1 designates the body of my burner which is surmounted by a pair of posts 2 that serve as supports for a frame comprising air direct ing members, and spreader wings.

3 is a wick tube which is mounted in the body 1.

The frame supported by the posts 2 coinprises a pair of side air directing members 4, which are inclined upwardly and inwardly relative to the wick tube 3, and the wick A in said tube, to which Wick the air for the supply of oxygen to the flame burning from the wick is controlled by passing between the members 4 and being partially confined thereby as it rises between said members. The frame also comprises the spreader wings 5 interposed between and connected to the air directing members 4 and which are inclined upwardly and outwardly relative to the wick tube 3. These spreader wings serve, when they become heated during the operation of the burner, to draw the flame burning from the wick toward them, thereby increasing the width of the flame and the illuminating power thereof.

No invention per 86 is herein claimed for the frame in so far as I have thus far described it, as its construction is known by me to be old. Experience in the use of lamp burners in which the described frame is employed, has shown that while very beneficial results are secured by the use of the frame in a lamp burner, there is an objectionable feature in the use of the burner in that the combustion of the illuminant, suchas kerosene, is not a complete combustion, and smoke is emitted from the burner.

For the purpose of securing complete combustion of the illuminant in the use of the burner, I provide means in connection with the air directing members of the frame surrounding the wick tube, more particularly at the upper edge of the air directing mem* bers, whereby a greater radiation of heat is secured from said air directing members, in order that the products of combustion and the air mingling therewith above the wick in the burner, may be kept at a heat to render such products of combustion more inflammable, with the result of their being consumed without the production of smoke.

I have found that the means best suited for the purpose stated, are supplemental plates 6 fitted to the air directing members 4 and spaced apart therefrom to provide air chambers 7 between the air directing members and said plates, as seen in Figs. III and IV. The plates are preferably located at the inner sides of the air directing members and are bent outwardly, so that they are clenched onto the upper and lower edges of the air directing members, as seen in Figs. I to III, inclusive. When both the air directing members and the plates 6 become heated during the operation of the burner, the heat, of a high degree, is radiated from the parts towards the flame that is burning from the wick in the burner, and the beneficial result herein referred to, in the combustion of the illuminant, results.

In Fig. V, I have shown a modification in which supplemental plates or strips 6 are fitted to the upper edges of the air directing members 4 only, to provide for the desired radiation of heat to the flame burning from the wick. This construction has been found beneficial to a certain degree, in connection plates embracing said air directing members 10 with the air directing members to increase the and partially spaced apart therefrom to pro-' efficiency of the burner, but the improvevide air chambers between the air directing ment in the efficiency is not as great as that members and plates, substantially as set 5 derived in the use of the radiation plates 6. forth.
